Imagine a busy building plunged into darkness during a fire or power cut – chaos, panic, and danger at every turn. This is why UK law makes emergency lighting non-negotiable. It’s not just a box to tick; it’s a literal lifeline. In this article, we’ll explain why emergency lighting is required, what BS 5266 covers, which buildings must comply, the types of emergency lighting, common compliance mistakes, and how to choose the right system. By the end, you’ll understand these requirements with crystal clarity – and you’ll see why acting with urgency and authority on this issue isn’t just wise, it’s legally and morally required.
Why Emergency Lighting Is Required
A ceiling-mounted emergency exit sign illuminates the escape route in a corridor, ensuring occupants can find their way out during a power failure.
Every year, power outages and fires put thousands of people at risk. Emergency lighting is required precisely to prevent tragedy when the mains lighting fails. UK fire safety law - specifically the Regulatory Reform (Fire Safety) Order 2005 – mandates that “emergency routes and exits requiring illumination must be provided with emergency lighting of adequate intensity” whenever normal lighting fails. In plain terms: if people need to evacuate a building, there must be reliable backup lighting guiding them out.
This legal requirement exists because when the lights go out, lives are on the line. Proper emergency lighting helps occupants evacuate safely, minimises panic, and allows first responders to do their jobs. Think of stairwells, corridors, and exit doors – if they vanish into darkness, the result can be deadly. BS 5266 and the Fire Safety Order are explicit: all escape routes, changes in direction, fire-fighting equipment, and final exits must be illuminated by emergency lighting. One overlooked dark corner or stair can cause disorientation or injury, turning an already dangerous situation into a disaster.
Failing to meet these requirements doesn’t just endanger people – it invites serious legal and financial consequences. Building owners and managers found non-compliant face heavy fines, possible jail time, increased liability for any harm caused, and even voided insurance coverage. In fact, a 2020 survey found 44% of firms in England lacked proper emergency lighting, risking “substantial fines or even prison sentences” for those responsible. In short, emergency lighting is required both by law and by common sense: it saves lives and protects you from immense liability.
What BS 5266 Covers
BS 5266-1 is the British Standard code of practice that practically writes the rulebook on emergency lighting. If the law tells you what you must achieve (safe, lit escape routes), BS 5266 tells you how to achieve it. This comprehensive standard provides clear guidelines on designing, installing, and maintaining emergency lighting systems. It covers every critical detail, including:
· Types of Emergency Lighting Systems – defining each category of lighting needed for safety.
· Design & Installation – how to properly locate and wire lights so they’ll perform when needed.
· Illuminance Levels & Duration – minimum brightness (illuminance) at floor level and how long lights must last on battery power (often at least 3 hours for most buildings).
· Response Times – how quickly emergency lights should activate (virtually instantaneously when power fails).
· Testing & Maintenance – requirements for regular testing (monthly function checks, annual full-duration tests) and keeping logs and certificates of compliance.
· System Reliability – ensuring there are no single points of failure that could leave occupants in darkness.
BS 5266 is essentially your blueprint for compliance. It’s developed by fire safety experts and referenced in building regulations and fire risk assessments across the UK.
Importantly, BS 5266 makes clear that its provisions are minimum standards – specific buildings or higher-risk environments might need even more stringent measures. By following BS 5266, you not only meet the law’s baseline, but you demonstrate due diligence in safeguarding occupants. If you’re involved in building design, management or contracting, BS 5266 is your authoritative guide – ignore it at your peril.
Which Buildings Must Have Emergency Lighting?
If you’re thinking “Does this really apply to my building?”, the answer is almost certainly yes. Emergency lighting requirements cover virtually all public, commercial, and multi-occupancy buildings in the UK. BS 5266 and fire safety laws apply to a wide variety of premises, including offices, shops, factories, warehouses, hospitals, schools, community halls, pubs, restaurants, hotels, hostels, and even tents or marquees used as venues. In residential buildings, common areas like corridors and stairwells of apartment blocks or dormitories are also covered. Essentially, anywhere people may need to evacuate in an emergency must have adequate emergency lighting.
It doesn’t matter if the building is old or new, large or small, or whether the power outages are frequent or rare – if people are inside, you have a duty to protect them. Most new buildings include emergency lighting as part of their design (as required by Building Regulations), but older premises must be brought up to standard as well. The law places this responsibility on the “Responsible Person” (such as the employer, building owner, or facility manager), who must conduct fire risk assessments and ensure appropriate emergency lighting is in place and working. If you fall into any role responsible for building safety – owner, landlord, facility manager, architect, electrical contractor – you are expected to know and comply with these requirements.
Remember: no building that is accessible to people is exempt from the need for emergency illumination. Whether it’s a high-rise office or a temporary event tent, if an emergency strikes and people need to get out, your building’s lights must lead them to safety.
Types of Emergency Lighting (Escape Route, Open-Area, High-Risk Task)
Not all emergency lighting is the same – BS 5266 defines several types of emergency lighting, each serving a specific purpose in keeping people safe:
- Escape Route Lighting: This is the most familiar type – lighting along paths like corridors, stairways, and exits that forms the means of escape. Its job is to clearly show the way out (including highlighting fire exit signs and safety equipment) so everyone can evacuate quickly and without panic. Even if smoke or confusion sets in, well-placed escape route lights (think of those green “EXIT” signs and illuminated arrows) ensure evacuees never lose their way.
- Open-Area Lighting (Anti-Panic Lighting): In larger rooms or open-plan areas (typically over 60 m² floor area), emergency lighting must prevent panic by providing a minimum level of illumination across the space. Imagine being in a big showroom, auditorium, or shopping centre when the lights fail – open-area emergency lights give enough light for people to stay calm and orient themselves. This lighting helps occupants identify an escape route from anywhere in the room. It’s especially crucial in venues where the public may be unfamiliar with the layout.
- High-Risk Task Lighting: Some locations involve dangerous processes – think of an industrial machine that needs a safe shutdown, or a laboratory experiment that shouldn’t be left mid-stream. High-risk task area lighting provides a higher illumination level focused on such tasks, allowing workers to terminate potentially dangerous processes safely before evacuating. Essentially, it prevents additional hazards (like machinery accidents or chemical spills) during an emergency by giving workers enough light to properly shut things down.
These three categories fall under emergency escape lighting – lighting intended to aid escape. There is also standby lighting, which is designed to allow normal activities to continue during a power cut. However, unlike escape lighting, standby lighting is not a legal requirement for life safety. Our focus is on the mandatory escape lighting types above.
When designing a system, you’ll typically use a combination: for example, illuminated exit signs and route lights in corridors (escape route lighting), bulkhead lights in open areas like lobbies or open-plan offices (open-area lighting), and specialised fixtures over any high-risk equipment (task lighting). Together, they ensure no matter where a person is or what they are doing, they will have light to navigate to safety or end a process securely.
Common Emergency Lighting Compliance Mistakes
Even with clear standards, many buildings fall short of emergency lighting requirements due to common mistakes and oversights. Being aware of these pitfalls can help you avoid them:
- Treating Emergency Lighting as an Afterthought: One frequent mistake is leaving emergency lighting design until late in a project. The result? Awkwardly placed fixtures, inadequate coverage, or costly rework to fix code violations.
Solution: Plan emergency lighting early. Integrate it into the lighting design from the start so that every escape route and open area is properly covered without clashing with aesthetics or other systems.
- Inadequate Coverage (Dark Spots): Under pressure to cut costs or due to simple oversight, some installations end up with unlit areas – maybe a shadowy corner of a staircase or an exit door with no light above it. Remember, every change of direction, stair, intersection, exit, and piece of fire-fighting equipment must be illuminated. Missing even one can cause a failure in a fire risk assessment or, worse, leave people stumbling in an emergency.
Solution: Conduct a thorough survey or professional lux-level mapping to ensure no escape route is left in darkness. Walk the building (or review plans) and verify all required points have emergency lights.
- Using Non-Compliant or Low-Quality Fixtures: Not all emergency lights on the market actually meet the standards. Tempted by a bargain, some choose cheap, uncertified fittings – a grave mistake. Inferior products often have shorter battery life, unreliable electronics, or insufficient brightness. If they aren’t UKCA or CE marked and tested to BS EN 60598-2-22 (the luminaire standard), they don’t belong in your building.
Solution: Always opt for quality, compliant equipment from reputable suppliers. It might cost a bit more upfront, but it ensures your system actually works when needed and passes inspections. High-quality units also tend to last longer, saving money (and headaches) in the long run.
- Neglecting Testing and Maintenance: An emergency lighting system is only as good as its maintenance regime. Yet a common compliance failure is irregular testing – or none at all. UK regulations (via BS 5266 / BS EN 50172) call for monthly functional tests (briefly simulating a power failure to check each light) and annual full-duration tests (typically for 3 hours). Skipping these tests means you won’t know a battery or lamp has failed until an actual emergency – an extremely risky gamble. Likewise, many forget to update their fire risk assessment and lighting scheme when changes are made (like new partitions or altered layouts), leaving new hazards unlit.
Solution: Establish a strict testing schedule and keep a logbook of results. Use automatic test systems or self-testing luminaires if possible, which make routine checks easier. And whenever the building layout or usage changes, revisit your emergency lighting plan and risk assessment.
- “Fit and Forget” Mentality: Some assume that once lights are installed, their job is done. This mindset leads to aging, out-of-date systems that no longer meet current standards or building layouts. The law, however, doesn’t accept ignorance as an excuse – you are accountable for keeping the system compliant over time.
Solution: Treat emergency lighting as a continuous responsibility. Keep your documentation (commissioning certificates, maintenance logs) up to date, replace batteries and luminaires before they fail, and stay informed about updates to standards or regulations. Regular refresher training or audits can help ensure nothing “falls through the cracks”.
By avoiding these common mistakes, you not only stay on the right side of the law but also fulfill the fundamental goal: keeping people safe no matter what happens. Each oversight you eliminate is one less risk during a crisis.
How to Choose the Right Emergency Lighting
Selecting emergency lighting for a building isn’t just a shopping exercise – it’s about choosing the right lifeline for when things go wrong. Here’s how to approach it with confidence:
- Assess Your Building’s Needs: Start with a thorough fire risk assessment. Identify all escape routes, open areas, and high-risk task zones that will need illumination. Consider the occupancy type (office, factory, school, etc.), the layout (small rooms vs. large halls), and any specific hazards (machinery, chemical processes). The assessment defines the scope: which areas require emergency lights and of what type.
- Follow Standards and Calculations: Use BS 5266 as your roadmap for design. This means planning for at least 1 lux along the centerline of escape routes and 0.5 lux in open areas at floor level (common benchmark values for compliance) – essentially enough light to see and move confidently. Ensure the chosen lights can meet these levels. BS 5266 also guides you on placement (e.g., above each exit door, at stairways, at changes of direction, near firefighting equipment, etc.). If you’re not an expert in lighting design, it’s wise to engage a specialist or use software tools provided by reputable manufacturers to model lighting levels and spacing.
- Maintained vs. Non-Maintained: Decide on the mode of operation for each area. Maintained lights are on at all times (often used in places like theatres, cinemas or crowded public venues where even the “normal” lighting is dimmed). Non-maintained lights only come on when mains power fails (suitable for most workplaces and offices where lights are normally on during occupancy). In many buildings you’ll use a mix: for example, maintained illuminated exit signs in areas used by the public, and non-maintained bulkheads in staff-only corridors. Choosing the right mode ensures you meet regulations without wasting energy or detracting from ambiance during normal times.
- Central Power vs. Self-Contained Units: Determine if you will use self-contained emergency luminaires (each unit has its own battery) or a central battery system. Self-contained LED units are common for ease of installation and have improved reliability (with 3-hour battery packs standard). Central battery or inverter systems can be useful for very large sites or where maintenance wants all batteries in one location, but they require robust wiring and monitoring. Evaluate your budget, building size, and maintenance capabilities – the goal is a system you can maintain easily and that will perform under duress.
- Quality and Compliance of Products: As emphasised earlier, insist on certified emergency lights from reputable brands. Look for the UKCA or CE mark and compliance with BS EN 60598-2-22 (the safety standard for emergency luminaires). High-performance LED emergency lights with good photometric data will ensure you achieve the required brightness without needing excessive fixtures. Also consider environmental factors: do you need IP65 weatherproof units for outdoor escape routes? High-temperature batteries for hotter areas? Only choose products that suit the conditions of your building and carry appropriate certification.
- Smart Testing and Monitoring: Modern emergency lighting can include self-testing features or be networked to a central panel. While not mandatory, these systems are game-changers for large facilities. They automatically test each unit on schedule and report any failures – saving labor and ensuring nothing gets overlooked. When choosing your lighting, explore options like self-test luminaires or automatic test systems. They may cost a bit more upfront but pay off by guaranteeing compliance and reducing manual effort. For example, a central monitoring system can alert you immediately if a battery fails, so you’re never caught off-guard.
- Consult Experts if in Doubt: Emergency lighting design can be complex. Don’t hesitate to consult a fire safety engineer or lighting specialist, especially for large or unusual buildings. They can ensure your plan meets BS 5266 and your products are appropriate. Manufacturers often offer design support – providing lux level calculations and product recommendations – take advantage of that. The bottom line is get it right the first time; it’s about safety, not trial and error.
By carefully considering these factors, you’ll choose an emergency lighting solution that fits your building like a glove – one that kicks in flawlessly when needed, meets all legal requirements, and instills confidence that you’ve done everything you can to protect lives.
